Enable Zephr to respect the s-maxage directive from origin responses for improved cache management and performance.

Zephr can respect the Cache-Control: s-maxage={seconds} header set by your origin service when determining how long content should be cached on the CDN edge. This behavior is not automatic, and it must be enabled per tenant using the configuration flag:

cdn.origin.honourSMaxAge

Once enabled, the Zephr CDN will use the origin’s s-maxage directive to determine cache freshness, improving performance while still allowing up-to-date content delivery.

Setting s-maxage=0 will prevent the response from being cached at the CDN entirely.

This feature is configured alongside other cache rules in the Configure Cache Rules section.
